Betel Nut River Buffalo

Betel Nut River Buffalo

The Betel Nut River Buffalo is a geographical indication certification trademark.

　　The Betel Nut River Buffalo (Bos bubalus) is the only river-type buffalo discovered in China. Historical records indicate that the Betel Nut River Buffalo has been raised and utilized in Tengchong County for over 200 years. It belongs to the Bovidae family, Bubalinae subfamily, and is a local group within the river-type sub-species of the Asian buffalo species. For a long time, Betel Nut River Buffaloes have been self-bred and self-raised by farmers, serving as a dual-purpose breed for milk, meat, and draft, with increasing emphasis on developing their dairy potential.

　　Production Distribution

　　The Betel Nut River Buffalo is primarily produced along the upper reaches of the Betel Nut River in Tengchong, mainly distributed in townships such as Houqiao, Zhonghe, Hehua, Mingguang, and Dianban, with scattered presence throughout the county.

　　Biological Characteristics

　　The Betel Nut River Buffalo is highly adaptable, mainly inhabiting low-altitude, hot valley regions, but can also grow and reproduce normally at altitudes between 500–2000m. These buffaloes have strong foraging abilities and are tolerant of coarse feed, consuming various types of green grass, tree leaves, and crop straw. They are gentle in temperament, easy to manage, though slightly nervous. Grazing is their primary feeding method year-round, supplemented with dry hay, corn, and crop straw in the evenings or during heavy labor. The Betel Nut River Buffalo has strong disease resistance; with proper management, they generally remain healthy. Commonly susceptible diseases include bovine hemorrhagic septicemia, blackquarter, liver fluke, paramphistome, roundworm, and certain gastrointestinal and metabolic diseases.

　　Physical Appearance

　　The Betel Nut River Buffalo has sparse, short hair, thin and shiny skin, and a dark black hide. Its coat is primarily black, with lighter coloring on the inner thighs and underbelly, and some juvenile individuals exhibit brownish tips on certain hairs. Approximately 20% of individuals show a “white sock” phenomenon, with white coloring on the lower limbs, ear hairs, and the fur around the lips. A small number of individuals have white foreheads or tail switches, with no signs of dappled, sandy, or white chest crescent markings. They have long, narrow heads, protruding foreheads without long hair; straight noses with black nasal mirrors and eyelids; thin ears with pointed tips, held flat; horn bases are flat, with horns forming spiral, small round, large ring, or forward-curved shapes—all black, with spirals being the most common (about 50%). They lack humps, dewlaps, or naval flaps; the size of the udder flap correlates positively with nutritional status. Cows have prominent milk veins and bowl-shaped udders, mostly dark brown, with pink udders in “white sock” individuals. The tail extends to the udder or partially to the hock, with moderately dense tail hair. Their hooves are solid and black. The neck is slender, of moderate length, horizontally set, resembling a deer’s neck. The head-neck, neck-shoulder-back, back-waist, and waist-rump junctions are well-integrated; the back is straight, the chest moderately wide, the belly good, and the rump sloping. Limbs are normally developed with good conformation; the body is sturdy and proportionate, with cows having well-developed hindquarters, appearing wedge-shaped from the side, overall of moderate structure. Measurements taken from 60 adult buffaloes (10 bulls and 50 cows) under normal rearing conditions, along with some buffaloes at various ages, show that adult bulls have an average height of 138.15±5.35cm, body length of 146.55±8.94cm, chest girth of 192.4±8.52cm, cannon bone circumference of 21.2±1.0cm, and weight of 475.58±55.48kg; adult cows measure 131.77±3.31cm in height, 139.16±7.99cm in body length, 194.22±9.66cm in chest girth, 20.44±0.85cm in cannon bone circumference, and weigh 430.18±57.15kg.

　　Production Performance

　　Female Betel Nut River Buffaloes reach puberty at 30 months, typically bred for the first time at 36 months. Estrus mainly occurs between August and November, with an average cycle of 21 days, lasting 2–4 days. The average gestation period is 310 days, with a lifespan of 20 years and a typical usage period of 15 years. Male buffaloes reach puberty at 24 months, showing mounting behavior, become sexually mature at 30 months, and are suitable for breeding at 42 months. This breed currently relies entirely on natural mating, with no artificial insemination used, maintaining a 1:30 bull-to-cow ratio. Breeding bulls are generally used for about 10 years, with a lifespan of approximately 20 years. According to data from 31 cows measured at a buffalo breeding farm, the Betel Nut River Buffalo has an average lactation period of 269 days, yielding an average of 2452 kg of milk per lactation, with the highest recorded yield at 3685 kg. Surveys among more than 60 lactating cows indicated an average milk production of about 1800 kg per cycle. In 2006, the Key Laboratory of Yunnan Agricultural University tested milk samples from 31 Betel Nut River Buffaloes, finding the milk to contain 6.73±0.47% fat, 4.05±0.14% protein, 4.99±0.06% lactose, 9.99±0.19% solids-not-fat, and 16.73±0.56% total solids. Slaughter tests were conducted on five adult buffaloes (two bulls and three cows) from the tested herd, yielding slaughter rates, lean meat rates, loin eye areas, and bone-to-meat ratios as follows: bulls averaged 44.51%, 33.37%, 35.8 cm, and 1:2.99, respectively; cows averaged 41.16%, 30.42%, 29.5 cm, and 1:2.67.
